We divide 646181 by 54
The aim is to understand the frequency of 54 in 646181.

Moving on to step 1:
6 divided by 54 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 54

Moving on to step 2:
64 divided by 54 is 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 54 from 64 leaves us with 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 54

Moving on to step 3:
The number 54 fits into 106 1 times, leaving a remainder of 52.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 52 after subtracting 54 from 106.
Grab the next digit (1) from the dividend, add it to 52, then carry on: 521 / 54

Step 4:
The number 54 fits into 521 9 times, leaving a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 119.0
If we subtract 486 from 521, we get 35.
Fetch the next digit (8) from the dividend, attach it to 35 and continue: 358 / 54

Step 5:
If we divide 358 by 54, we get 6 and a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 1196.0
If we subtract 324 from 358, we get 34.
Grab the next digit (1) from the dividend, add it to 34, then carry on: 341 / 54

On to step 6:
341 divided by 54 is 6 with a remainder of 17.
The next digit of our result is 6. 
Result so far: 11966.0
If we subtract 324 from 341, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
The number 54 fits into 170 3 times, leaving a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 11966.3
The remainder is 8 after subtracting 162 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
80 divided by 54 is 1 with a remainder of 26.
The next digit of our result is 1. 
Result so far: 11966.31
If we subtract 54 from 80, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 9:
260 divided by 54 is 4 with a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 11966.314
Deduct 216 from 260 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 10:
When dividing 440 by 54, we get 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 11966.3148
Subtract 432 from 440 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
80 divided by 54 is 1 with a remainder of 26.
The next digit of our result is 1. 
Result so far: 11966.31481
Deduct 54 from 80 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
260 divided by 54 is 4 with a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 11966.314814
If we take 216 away from 260, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 13:
54 goes into 440 8 times with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 11966.3148148
The remainder is 8 after subtracting 432 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
When dividing 80 by 54, we get 1 with a remainder of 26.
The next digit of our result is 1. 
Result so far: 11966.31481481
Subtracting 54 from 80 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The quotient of the division is 11966.31481481, and the remainder is 2.6e-08.
